[LS9658]

After I ran this program, there was a problem in the result output:

> IntGenicPlot('evm.model.HIC_ASM_13.455_T01', mygtf, association = myassociation, hapmap = myhapmap,
           hapmap_ld = myhapmap, threshold = 6.64, up = 2500, down = 100, leadsnpLD = FALSE,
           marker2highlight=mymarker2highlight, link2gene=mymarker2link, link2LD=mymarker2link)

Linkage Disequilibrium (LD) estimation on genotypes:
# of samples: 345
# of SNPs: 79
using 1 thread
method: correlation
LD matrix: the sum of all selected genotypes (0,1,2) = 32048

Press to see the next picture:
There were 50 or more warnings (use warnings() to see the first 50)
Warning message:
1: In lapply(X = X, FUN = FUN, ...): NA was generated during the forced change

Thanks for all help to me
